lil v improved" pocket-knife comprises a handle 10, a blade 11, and means foroperatively holding the same together consisting of a rivet l2 and a slide 13 mounted on one end of the said rivet 1i. i

The blade 11 is ordinary and may have any style of form and size as desired, and comprises a head 14 of the iisual form at the end that is joined to the handle 10., the said head 14 comprising a generally straight edge 15 on the side of the cutting edge 16 substantiallvin parallelism therewith, and ofiiset slightly outwardly relatively to the same;

, a straight edge 17 at the extreme inner end,

extendingacross the axis; a straight edge f 18 parallel with the first mentioned straight edge 15 and. oil-set inwardly relatively, to the back edge 19 and connected to the said back edge 19 by a shoulder 20; and having a hole for the pin 12 in the portion hounded hv the said straight edges 15, 1?, and 18. The edges 15 and lli extend longitudinally of the blade and are substantiall parallel with the axis.

The handle 10 is formed of a single-z piece of sheet material, the hlanl: therefor, as shown in Fig. 4. comprising at one end, shown at the left in the said figure, the ham die side 21. being); the side that in the rear in Fig. l. and at the right end the front handle aide edges of the said right or front handle side 22, adjacent the outet end thereof- The left or rear handle side 21 is provided with a hole adjacent the outer end for the pin or rivet l2 and the right'or front handle side 22 has a transverseslot- 26 aceiit the outci 'end that is a lit for the said rivet 12. The flange 24 is turned inwardly along the line 27, that is coincident with the back edge 28 of the handle side 22 suitably tojextend 'Pntenteddan; 23,191'3. Application filed.

across the back portiOnofthe handle struc tore so as to cooperate with the various edges of the head lei of the blade lljfor' holding the blade in the usual, different positions,

comprising the closed, hall open, and lull open positions. Thus the fia-ngc 245 is of sufficient length to engage Withthe straight edge portion 15 that is parallel with the cutting edge 16, which is the longest of the edges that boundthe head'l l and comprises a slight excess oil length, and fills a portion only of the rear of the ha ndle structure, the,

reinainderof the said rear hein'gopen.

'lhchandle sides 21 and 22 are shaped to provide the desired contour of the handle striict-ure and the blank is folded along two transverse 11119329 at the junctions of the sides '21 and 22 with the neck 23,the said lines 29 being spaced suit-ably TZGPYOYldB the proper thickness or depth for housing the blade 11, the sides 21 and 22 being brought into parallelism, with the slot 26 opposed to the hole 25.

The rivet or pin 12 has the rear end positioned in the hole 2 5 and headed over, the. body portion extending: through the blade ll and througl'i the slot 26, and the front end extending through a hole in the slide 13 and being; headed over suitably to hold the said slide L?- in slidingengagement with the outer face oi? the "front handle side 2-2.

The slide 13 serves as a. button or cap to cover the slot 26 and to-hold the handle ill and the blade 11 operatively connected.

'l he nech 23 serves to fixedly connect the handle sides 21 and 22 generally and at the same time beoauseof the resiliency of the material of which. the blank is formed, Serves to resiliently connect the said sides,permit:

- ting of relatively lateral movement of the two the said sides 21 and being 7. connected at the middle ol the lilanh by the neck 23, as shown slightly reduced relatively sides. one side moving slightly to one side relatively to the other responsive to pressure-g the neck 25; yielding to suchpressure. Thus the neck 23 serves as the equivalent of a hinge or pivotal connection for the handle sides, permitting the same toibe moved in substantial parallelism to the extent necessary to permit the blade 11 torbeshiftedfrom one position to the other and serves as v aspring" to hold th'e'parts in resilient en gagement as is usual in pocket-knives. The

neck 23 is hardenedand tempered suitably to, serve as a s rin as described.

lhe rivet 12 travels in the slot 26 as the handle sides 21 and 22 are moved in the mannerdescribed. 4

v Instead of having only a single blade 11 I may use two blades 11 and 11- mounted on the same rivet 12 both of Which may be formed and operated as in the case of the said blade 11.

By having the bridge, or neck 23 appreand are found generally in ordinary knife structures. For instance, the corners of the handle sides adjacent the neck 23 can be apt preciably rounded, as shown, thus presenting the appearance of a knife of ordinary structure. Also the end of the handle is closed, as. in the case of an ordinary knife.

Of particular importance however is the fact that the neck or bridge serves as a positive spacer for'spacing the handle sides suitably to insure an open space'for housing the blade in the closed position, thus permitting the free opening and closing of the blade, .by preventing the closing of the handle sides over the blade receiving space, when the blade is open and preventing the handle sides from being forced against the blade and pinching the same when in the closed position. v

I claim as my invention In combination in a pocket knife having a handle formed of a single piece of sheet material and a blade, the said blade being a operatively connected to one end of the handle structure, and the said handle structure comprising a pair of handle sides opposed one to the other and separated by a blade receiving space, the said blade filling the said spaceat one end of the said handle sides, means for holding the other ends of the said handle sides in spaced relation comprising a bridgeextending across the end portions of the saidhandle sides, and the said bridge-serving as aspring member for resiliently holding the said blade in the position to which it is handle.
